Abstract. Solfiyeni, Winata F, Mildawati, Marisa H. 2024. Vegetation composition, structure and association at site invaded by Calliandra houstoniana in Bung Hatta Grand Forest Park, West Sumatra, Indonesia. Biodiversitas 25: 3608-3616. Invasive plants are plants that can aggressively dominate an ecosystem, thereby disrupting the balance of the ecosystem. Kaliandra (Calliandra houstoniana (Mill.) Standl.), an invasive alien plant species, has notably invaded several conservation areas in Indonesia, including Bung Hatta Grand Forest Park, West Sumatra. This study, conducted from October 2023 to February 2024, aimed to analyze the composition, structure and association of vegetation community affected by C. houstoniana and investigate the association between C. houstoniana and other species within the park. Sampling was conducted using the quadrat method by establishing a 20 × 50 meter observation plot, subdivided into ten 10 × 10 meter subplots for tree level; 5 × 5 meter for sapling and 2 × 2 meter for understorey. We identified all plant species within the sub-plots and measured environmental factors including light intensity, temperature and soil pH. Within the sampling plots, there were 11 families, 13 genera and 14 species at tree level with C. houstoniana exhibited the highest Importance Value Index (IVI = 62.96%). At sapling level, there were 9 families and 12 species with the dominance of C. houstoniana (IVI = 168.47%). Understorey was composed by 15 families and 19 species with Clidemia hirta (L.) D.Don as dominant species (IVI = 29.26%). Shannon-Wienner diversity index (H') was moderate where index for tree, sapling and understory was 2.32, 1.69 and 2.7, respectively. Only a few species managed to coexist and withstand the invasion of C. houstoniana. Association tests, including the Chi-Square Test and Jaccard Index, indicated no significant association between C. houstoniana and other species. The results of Principal Component Analysis (PCA) show that environmental factors, especially light intensity and air temperature, greatly influenced the presence of the two dominant species C. houstoniana and Falcataria falcata (L.) Greuter & R.Rankin, while the presence of Pandanus sp. is influenced by soil pH. The study demonstrated that C. houstoniana negatively impacts the diversity of local species, reducing overall diversity levels in Bung Hatta Grand Forest Park.

Abstract. Mildawati, Hanafi SPS, Putri E, Aziz MA, Ivani S, Nurhasna, Solfiyeni. 2025. Micromorphological analysis of spores on various species of pteridophytes: Implications for species identifications. Biodiversitas 26: 2332-2338. Pteridophytes, a group of vascular plants, play a critical role in ecosystem balance. However, taxonomic challenges persist in identifying and classifying their species. Spore micromorphological characters, unique to each species, offer a potential solution to these issues. This study aimed to examine the spore micromorphology of several pteridophyte species growing on the Universitas Andalas campus, Padang, Indonesia. The species examined included Antrophyum callifolium, Asplenium nidus, Davallia denticulata, Pteris vittata, Pyrrosia adnascens, P. longifolia, and P. piloselloides. Spore samples were observed using a binocular light microscope with a magnification 40x objective lens and documented with the OptiLabView4 application. The results revealed that most pteridophytes spores studied exhibited a monolete laesura type with an ellipsoid shape, except for A. callifolium and P. vittata, which showed a trilete laesura type with a tetrahedral shape. Exospore ornamentation was varied: verrucate in A. callifolium, A. nidus, D. denticulata, and P. vittata; reticulate in P. adnascens and P. longifolia; and echinate in P. piloselloides. Spore sizes were categorized as medium (25-50 ?m) for A. callifolium, A. nidus, D. denticulata, and P. vittata.; and large (60 ?m) for P. adnascens, P. longifolia, and P. piloselloides. Spore micromorphology of pteridophytes on the Universitas Andalas campus, revealing significant diversity in size, shape, and ornamentation.

Abstract. Nurhasanah D, Solfiyeni, Mufti HM, Maideliza T. 2025. Diversity and composition of invasive understory plants in Kapalo Banda Taram Ecotourism Area, West Sumatra, Indonesia. Biodiversitas 26: 4500-4510. Invasive plants are species that establish and spread rapidly outside their natural habitats, often dominating new environments. This study aims to analyze the composition, structure, and diversity of invasive understory plants (seedlings and ground vegetation) in the Kapalo Banda Taram Ecotourism Area, Lima Puluh Kota District, West Sumatra Province, Indonesia. This study used a survey method using two transects with purposive sampling. Location 1 (transect 1) in the eastern part and Location 2 (transect 2) in the southern part of the area. The length of each transect was 50 meters, and along the transect, 25 plots measuring 2×2 meters were systematically placed on each transect. In each plot, observations were made regarding the presence of species, the number of individuals, and environmental factors. Results showed that in Location 1, there were 18 families, 26 genera, 26 species, and 1,213 individuals of understory plants, including 9 invasive families, 14 genera, 14 species, and 1,168 individuals. In Location 2, there were 9 families, 16 genera, 17 species, and 734 individuals, with 5 invasive families, 10 genera, 10 species, and 614 individuals. The dominant families in Location 1 were Melastomataceae (31.16%), Cyperaceae (28.85%), and Poaceae (28.28%), with Cyperus rotundus as the most dominant species (IVI: 43.92%). In Location 2, Asteraceae dominated (50.14%), with Chromolaena odorata as the most dominant species (IVI: 57.52%). The Shannon-Wiener diversity index (H') indicated moderate diversity, with values of 2.34 and 2.26. Canonical Correspondence Analysis (CCA) revealed that environmental factors such as light intensity, humidity, temperature, and soil pH significantly influence the distribution and dominance of invasive understory species. This study provides valuable insights into the management of invasive plants in the Kapalo Banda Taram Ecotourism Area, aiding conservation and sustainable tourism efforts.
